To all whom it may concern.-

Beit known that I, JAMES W. GLADSTONE, a

, subject of the King of Great Britain, and a resident of West Orange,in the State of New Jersey, have invented certain new and usefulImprovements in Batteries, of which the following is a specificationaccompanied by drawlugs.

This invention relates to batteries, but more particularly to primarybatteries; and its objects are to improve upon the construction of suchbatteries, secure simplicity and compactness, and increase the internalconductivity.

Another object of the invention is to improve upon the construction ofthe sustaining-frame and clamping devices carried thereby for one of theelectrodes.

Further objects of the invention will hereinafter appear.

To these ends the invention consists of a battery for carrying out theabove objects embodying the features of construction, combinations ofelements, and arrangement of parts, having the general mode of operationsubstantially as hereinafter fully described and claimed in thisspecification and shown in the accompanying drawings, in which- Figure 1is a side elevation, partly in section, of a battery embodying theinvention.

Fig. 2 is a vertical sectional detail view of the clamps. Fig. 3 is anenlarged sectional detail view of the means for locking the clamps. Fig.4 is a view similar to Fig. 3, but with the locking device in adifierent position; and Fig. 5 is an enlarged detail perspective view ofthe eccentric locking device.

Referring to the drawings, A represents a suitable container or vesselfor the battery, provided with the cover B of any suitable material, asporcelain. As shown, a rubber ring G encircles the cover for cushioning.the same within the container. The negative plate D may be of copperoxid properly molded, and it is supported from the cover B within thevessel by a supporting-frame or hanger,shown in this instancesubstantially U-shaped and consisting of the side bars E and cross-barF. The hanger may be of plain copper wire of a suitable gage bent intothe desired shape and in this instance provided with screw-threaded endsG, afiording provision for supporting the hanger from the cover by meansof the nuts H. Bindingscrews are provided for attaching theconnecting-wires.

The hanger is provided with depending spring-clamps J and K, formed,preferably, of perforated metal, while means are provided for lockingthe free ends of the clamps together. The clamps J and K, as shown, arebent around the cross-bar F of the hanger and secured by rivets L. Thefree ends of the clamps, as shown, are bent inwardly and overlap and areprovided with registering apertures through which the eccentric lockingdevice 0 is passed. The locking device 0 comprises a cylindrical key orstud provided with a cut-away portion P and a head Q. A removable pin Rpasses through the device 0 for afiording provision for manipulating themachine with the fingers. The clamps J and K have sufficient springaction to normally force them apart, as shown in Figs. 2 and 3. In thesefigures the clamps are separated to the fullest extent permitted by thelocking device, because the cut-away or eccentric portion P of the keyis in such position that the inwardly-bent portion of the clamp K ispermitted to enter said cut-away portion. By turning the key to theposition shown in Fig. 4 the wide portion of the key enters the aperturein the inwardly-bent free end of the clamp K and forces the two clampscloser together, thereby tightly clamping the electrode D between thesame. Any desired number of the spring-clamps may be used, I havingshown but two for convenience of illustration. I am also not to beunderstood as limiting myself to the particular form of eccen triclocking device shown,but have illustrated the preferred form of theinvention.

7 The positive zinc plates S are arranged at each side of the negativeplate D and are preferably cast into a U-shaped casting suitablysupported from the cover B by means of the screw-threaded bolt or rod T,having the nut U and binding-screw V.

Obviously some features of this invention may be used without others,and the invention may be embodied in widely varying forms.

Therefore without limiting the invention to the construction shown anddescribed nor enumerating equivalents, I claim and desire to obtain byLetters Patent the following:

1. In a battery, the combination with an electrode and asupporting-frame or hanger, of a plurality of spring-clamps dependingfrom said hanger, and means for locking the free ends of said clampstogether, for substantially the purposes set forth.

2. In 'a battery, the combination with an electrode and asupporting-frame or hanger, of a plurality of springclamps dependingfrom said hanger, the free ends of said clamps having perforationsadapted to substantially register, and a locking device cooperating withsaid perforations affording provision for loosening and tightening theclamps, for substantially the purposes set forth.

3. In a battery, the combination with an I electrode and asupporting-frame or hanger, of a plurality of spring-clamps dependingfrom said hanger, the free ends of said clamps being provided with alocking device affording provision for loosening and tightening theclamps, for substantially the purposes set forth.

' 4. In a battery, the combination with an electrode, and asupporting-frame or hanger, of a plurality of spring-clamps dependingfrom said hanger,the free ends of said clamps being provided with aneccentric key or locking device for loosening and tightening the clamps,for substantially the purposes set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JAMES W. GLADSTONE.
